Several countries in the region have undertaken tax reforms and introduced simplified tax regimes for SMEs since 2019. In Argentina, the monotributo range has been extended to micro-enterprises and individual entrepreneurs, accompanied by a "bridge regime" facilitating the transition from monotributo to a full corporate tax regime.
In Brazil, the government implemented measures to simplify tax filings and payments through Simples Nacional and Microempreendedor Individual (Individual Microentrepreneurs, MEI) schemes, with ongoing efforts through two permanent committees dedicated to tax reform.
Chile is currently undergoing a comprehensive tax reform, introducing a VAT regime for service sales, particularly impacting small-scale enterprises in the service sector. While maintaining a special tax regime for SMEs, Chile has introduced fiscal incentives for startups and those undergoing formalisation, along with a transition “bridge” for SMEs moving to the standard corporate tax regime. Uruguay has implemented a similar transition measure.
Colombia’s progressive tax reform since 2018 aims to enhance tax compliance for small-scale enterprises, while Ecuador introduced a simplified tax regime for micro-enterprises called Régimen Simplificado para Emprendedores y Negocios Populares (Simplified Regime for Entrepreneurs and Popular Businesses, RIMPE). This initiative imposes a turnover tax of 1 to 2% on enterprises with an annual turnover between USD 20,000 and USD 300,000.
In Mexico, the Servicio de Administración Tributaria (Tax Administration Service, SAT) introduced the Régimen Simplificado de Confianza (Simplified Trust Regime, RESICO) to simplify tax-filing procedures for individual entrepreneurs and small-scale enterprises. This initiative imposes a turnover tax ranging from 1 to 2.5% for enterprises and individual entrepreneurs below a set annual turnover threshold, contributing to lower tax charges and reducing enterprise informality.
Paraguay has also been actively implementing tax reforms since 2019, involving a reduction in the number of taxes on private enterprises, simplification of tax-filing procedures, and the introduction of a simplified tax regime for SMEs.
